In conjunction with today’s 2016 #41 issue of Weekly Shōnen Jump in Japan, Bandai Namco’s official website for Dragon Ball Z: Extreme Butōden has announced a forthcoming patch that will allow cross-game battles (クロス対戦) with the upcoming One Piece: Great Pirate Colosseum, also on the Nintendo 3DS.
One Piece: Great Pirate Colosseum hits the Nintendo 3DS in Japan 21 September 2016 for ¥5,700 + tax. The patch enabling cross-game battles — which will include both local and online multiplayer — will hit later this year in November.
Both Dragon Ball Z: Extreme Butōden and One Piece: Great Pirate Colosseum are developed by Arc System Works for Bandai Namco on the Nintendo 3DS, with the former seeing an international release last October following its June 2015 release in Japan.
